A traction bar would have to go on where the spring is atteched soild to the frame. so on a yota it would have to go on the front.

now that being said, a trac. bar like the one mikey posted up that has a shackle on it would go on the back. butt it would not stop all the wrap as it would have some flex in the shackle. butt it would likely stop enuff to do the job. and no a slip jount would just defeat the porpuse. (where a pic. of Flipper when you need one? )
